Electronic Sound is George Harrison's second solo album, and the second and final record released on the Beatles' short-lived Zapple Records (an offshoot of Apple Records), before it was folded at the insistence of The Beatles' then-manager Allen Klein. Released in May of 1969, it features two lengthy pieces - one per side on the original vinyl release - performed on the Moog synthesizer.

Portions of white noise from "No Time or Space" are used throughout "I Remember Jeep", one of several jams included on Harrison's third solo album, All Things Must Pass, released in 1970.

The cover of Electronic Sound was painted by Harrison himself. The inside sleeve included minimal notes on the album, and a quote, attributed to an 'Arthur Wax': "There are a lot of people around, making a lot of noise; here's some more."

Due to its experimental and highly uncommercial nature, Electronic Sound failed to chart in the UK, and barely made the US Billboard album chart, peaking at #191. Synthesist Bernie Krause later pursued legal action against Harrison, claiming side two of the record was essentially him demonstrating the Moog III to Harrison (as detailed in his book Into A Wild Sanctuary). Krause's name was originally featured on the front cover just under Harrison's, but was painted over in silver at Krause's insistence just before release.

The album was issued on CD for the first time in late 1996.
